FROM 1980 to 2013, the International Journal of Epidemiology carried out 174 surveys across 63 countries to determine the global prevalence of common mental disorders. The systematic review and meta-analysis revealed that one in every five respondents (17.6%) met the criteria for a common mental disorder, and 29.2% of the respondents experienced a common mental disorder in their lifetime.
The same study suggests that women have higher rates of mood (7.3%:4.0%) and anxiety (8.7%:4.3%) disorders, while male respondents have higher rates of substance use disorders (2.0%:7:5%).
